Subject: [PATCH v3 5/7] max8903: removes non zero validity checks on gpios.
Date: Fri, 17 Jun 2016 15:00:24 +1000 [thread overview]
Message-ID: <1466139626-51434-6-git-send-email-chris@lapa.com.au> (raw)
In-Reply-To: <1466139626-51434-1-git-send-email-chris@lapa.com.au>
In-Reply-To: <1464849897-21527-3-git-send-email-chris@lapa.com.au>
From: Chris Lapa <chris@lapa.com.au>
Prior to this commit a zero gpio was treated as invalid. Whereas
gpio_is_valid() will treat a zero gpio as valid.
This commit removes the confusion and explicity uses gpio_is_valid()
throughout. Which in turn results in several of the error messages becoming
redundant and thus removed.
